Q. Why are oil stains so difficult to remove from concrete?
A. Concrete is like a hard sponge. Depending on porosity, time and type of hydrocarbon, oil stains can penetrate deep into the pores of concrete and become hard to reach to clean.
Q. After using Pull It Out I have a slight white residue remaining - why?
A. Occasionally a white residue may be evident after use, particularly on rough, very porous surfaces. This will fade over time. It is recommended to always test in an inconspicuous area for desired results. The Advanced formulation is far less likely to leave any residue, we’ve seen little to none in our tests.
Q. Can I use Pull It Out indoors?
A. It is designed primarily for outdoor use as it can become dusty after drying and brushed to remove.
Q. How long does it take to dry?
A. Depending on heat and humidity, it can range from 1-12 hours.
